Can't smell Fuel / No spark.

[SubCool]

Im sure a few of you know of my problem with the car not firing.

http://www.shoforum.com/showthread.php?t=67417&page=2

I havent gotten a responce to one of my questions tho.
If the problem is my DIS, would that prevent the car from injecting fuel into the cylinders?

Im still working on cornering the problem.

i havent seen too many guides of installing a MSD system. Anyone know of one? (i am still searching tho)

just because you cant smell it doesnt mean its not there, did you check for pressure at the fuel rail? Pull a plug wire(spark plug end) hold it near the motor(metal ground) have someone crank and look for a spark.

yeah, i did all that.
(mentioned in the linked site)

I would just think with the amount of times i turn the engine out there while testing things, i would smell the fuel by now. I know when the car is working normally, and the battery use to die quickly [doesn't sound right does it]; I use to have to crank it alot to jump it, I could smell the fuel then. and i didnt have a cylinder open.

try running a wire from neg battery post to one of the 4 5.5mm bolts on each corner of the dis module to make sure you have good ground

Are all of the screws in the DIS module?

if your not getting a fuel pump noise you got a few things that it would be, PCM where the fuel pump relay hides which almost never goes bad fromw hat i understand, or fuel pump.
but check the fuel rails for pressure first.

goes from what your other thread has stated my bet is check the sensors and all that good stuff under the dash, also take the column shrouds off and make sure the main harness into the steering column is night and tight, if thats lose it makes a annoying higher pitched buzzing.
for sure tho check all grounds wiring and the black boxes and all under the dash.

just please dont mess with any air bag modules with the battery on.

turst me you might have to check recheck and check again to find out what it is you mighta pulled a wire broke some sort of relay box or soemthing stupid but from what your other thread is my bet goes on some sort or wiring and not really the fuel.

also if that wiring pack on the steering column isnt secure the fuel relay wouldnt let the fuel pump kick on.

Have you tried hot wiring the fuel pump to get fuel? When my fuel pump relay wennt out I ran a wire from a keyed port on the fuss box to the roll over relay in the trunk ans powered it when the key was turned on, engine fired right up, so I had a bad fuel pump relay.

What I see happening here is a lot of putting the cart before the horse. All good intentions from people trying to help, but if we jump around all over the place, he could be checking different things forever.

Here's what you need to do:

-Forget the MSD ignition stuff. The stock stuff is more than adequate, most of the boosted and nawzed SHO's I've seen still have the stock ignition with no issues. The MSD isn't going to solve your problem. Not to say that it's not cool to have, just not necessary, and one more variable in figuring out what's wrong with your SHO.

-Check for fuel pressure at the rail. I'm pretty sure most big chain auto stores rent fuel pressure testers.

-Check for spark as described before, with a plug pulled and grounded.

-Let us know what you find out.

hey, sorry i didnt get the notice the msg in my mail. or i did. w.e.

i was only asking aobut h MSD because the replacement Coil Pack and DIS combined are more then the price the MSD i can get. Only reason why i considered it.

every time i prime the engine, the pressue throught the rail returns. Whats the exact pressure? i dont know yet. i wil ahve to go rent/buy a tester. but i do poke at it.. and the entire engine bay gets hit.

Spark, Already tested for spark. grounded the spark plug and all.. nothing.
That why i was asking about fuel int he cylinder. Cause when i was testing, i didnt smell any.

Thanks guys.

You can find the info you need to test the DIS here.

Wow, thats great.
i've been looking like crazy for that stuff.


Well, It might be a day before i can test this. I have to read it over and print it. Thanks alot..

I was doing some other reading. Just to verify, Another thing about MSD ignition. is it an Add-on, not a replacement for the DIS and Coil pack? im still tring to understand the installation and use. That and, the coil pack that comes with it, is a 4 stud. how do you wire 6 cylinders to 4 studs?

hey guys,
im back. I got the DIS and the MSD ignition. I have the MSD on the side, but i did install the DIS and the COIL pack.
Still no spark.

Any ideas? im staring at these diagrams.
I dont know what to do.

Ok, With some reading up, and more running around. I guess we are back to the Grounds and CPS.

I have done a search through here, but i guess im using the wrong key words. But i am tring to find if anyone had notated where ALL the grounds are, to check for a missing or bad ground. Im Pretty positive that my grounds are connected, but u never can tell.

the other thing i ran into was this thread:
http://www.shoforum.com/showthread.php?t=57560

where he mentions his problem, which is identical to mine. And his resolution. Which i think was great of him.

It states that the cps wasn't within 1/16 of timing belt pulley. I'll admit, When i installed the pully. I didnt measure it. I didnt have a tool. But, in safe keeping of the CPS, I did push the crank as far as i could in so that the pully was just barely not going to hit the CPS. There is that flang(??) that has that gaping hole. i guess to install the cps. I dont really understand how the cps reaches the pully to get its readings, if it does sense the pulley.
Basically, i don't get it.
It sounds like it would possibly be my problem. But it is at the bottom of everything, and the only way to see it is by taking the belts off again. Not something i wanna do, just for the giggles of measuring the gap. Especially if that isnt the issue.
As mentioned in the linked thread, it seems like there is no way to test it other then looking at it. So, i guess if anyone could tell me some background info, or cautions about CPS installs, or gaps. It would be great.

So what do you all think?
Right track? Wrong Track?

Ok, Now to catch up.
I am having a new problem.
I replaced the CPS.

and now the car has spark. its cranking.. and there is fuel through the lines.. with pressure. But the car wont turn over. All it does is crank.
SO now what?
I dont have any of the accessories on. im afraid to put it all on, and than have to take them off. The belts are off, its open to only the timing belt.

What could be the issue?

You mean the engine turns over but does not start because there is no spark?

No there is spark,
But it does not start.
